Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, pry bar, and a flashlight.
Ensure vehicle is on a level surface and secure the parking brake.

2. Lift Vehicle

Use the jack to raise the front of the vehicle.
Place jack stands under the vehicle for safety.

3. Inspect Suspension Components

Visually inspect control arms and bushings for cracks or excessive wear.
Use a pry bar to check for play in the bushings and control arms.
Tighten any loose bolts to manufacturer specifications.

4. Check CV Joints

Inspect the outer CV joint for torn boots or grease leakage.
If damaged, replace the outer CV joint or the entire axle assembly as necessary.

5. Inspect Wheel Bearings

Spin the wheel by hand and listen for any grinding noise indicating bearing failure.
If faulty, remove the wheel and replace the wheel bearing as needed.

6. Examine Brake Components

Check brake calipers and brackets for looseness.
Tighten any loose components and ensure pads are properly seated.
